A DNA sample contains 30% cytosine. What percentage of the sample would be thymine?
julia-pushkina [17]

Answer:

30% Thymine

Explanation:

If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.

Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.

<u>Therefore:</u>

30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
